LOOPBACK-DETECT-MIB

Description: D-Link MIB defining objects for loopback detection, allowing the switch to identify and respond to network loops on access ports.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

LOOPBACK-DETECT-MIB is a D-Link proprietary enterprise MIB that defines objects for the loopback detection feature found on D-Link managed switches, which identifies when a port's outgoing traffic loops back into the switch, a common cause of broadcast storms. No sample objects were provided, but per the module description this MIB governs the switch's proprietary loopback-detection management structure, typically covering global/per-port enable settings and per-port loop status. Its monitoring role is squarely fault detection at the hardware/network layer: it would let an administrator see which physical ports have detected a loop condition and whether the switch has automatically shut down or blocked that port in response, which is critical for maintaining switch and network stability. As a D-Link proprietary feature MIB, it doesn't appear to depend on external standard MIBs beyond the base D-Link enterprise MIB tree. It is deployed on D-Link managed switches in LAN environments prone to accidental network loops, such as offices and campus wiring closets. Engineers can download the LOOPBACK-DETECT-MIB file directly to load it into their MIB browser.

No sample_objects were provided for this module, so a concrete object-level scenario can't be grounded in real names; based on the module's stated purpose, an administrator would typically monitor a per-port loop-detected status object and a global enable/disable control to confirm loopback detection is active and to identify which port triggered a shutdown after a cabling mistake created a physical loop.

Detects and manages network loop conditions on switch ports and VLANs to prevent broadcast storms.
